Putting a wind farm into operation requires many years of work, permits and data collection. As if it were a meccano, the operators fit the pieces one by one until they exceed 100 meters in height of a tower that will be key to locating the wind turbines.
The tall towers are actually weather stations that help us to measure the wind accurately and precisely: its speed, direction and also its temperature.
Your data, collected for a whole yearare necessary to see if the conditions are met to later install a wind turbine in that place.
And although this is the usual procedure up to now, the laser lidar He comes to change everything. Or at least, to make things easier.
It is a laser that emits pulses of light that bounce off aerosols in the atmosphere and return to the device. The laser allows data to be recorded up to 300 meters, above the maximum height of the blades of the most modern wind turbines.
In this way, the time it took for that impulse to go and return is measured and an accurate measure of wind speed and direction can be calculated.
Thus, this laser gives us the same data, but with fewer towers and in just a few months, at the same time that it reduces the time that operators have to hang tens of meters high.
